Brighton & Hove Albion's home ground The Amex Stadium could host a European Rugby Champions Cup semi-final next month.
Wasps will play their last-four match at The Amex against either Leinster or Bath if they overcome Toulon in this weekend's quarter-final at the Stade Felix Mayol.
It would be the second rugby game to be played at The Amex in as many months following the Under-20s Six Nations match between England and France.
If Wasps do beat Toulon, the semi-final on the South Coast will take place on the weekend of 18-19 April.
